Description
Technical field
The utility model relates to a kind of gas cabinet, relates in particular to a kind of gas cabinet piston and lands automatic buffer device.
Background technique
Piston is the heart of gas cabinet, and for fear of piston and base plate collision, traditional rubber membrane gas cabinet adopts and stops in advance giving vent to anger; Slow down, the way of slowly landing is that is: when the gas cabinet piston drops to about total travel 20%; Close the coal gas terminal valve, let the gas cabinet piston stop; Terminal valve again turns on the gas-fire when the needs air inlet.If piston need land,, let the gas cabinet piston reduce to base plate slowly with the rate of descent of strict control piston.After piston landed, the piston plate of traditional gas cabinet was fallen above the arch sheet.Because the piston plate of traditional gas cabinet does not have skeleton, be flexible board, and the rate of descent of piston is very fast; Can surpass 5m/min,, can let piston plate damage when piston lands if so fast speed does not have measure; Therefore, " the converter coal gas purification recovery technology rules " of China metallurgy industry establishment (No. 548, smelting peace ring word) (88 years) regulation: " the maximum reserves of gas cabinet should not surpass 95%, and minimum reserves should be less than 20%; when the reserves of gas cabinet drop to 30%; then should get in touch with the air feed unit, as not continuing to reclaim coal gas, should notify the user preparation of stopping the supple of gas or steam." these rules do not become so far, and this gas cabinet has also kept original structural type so far, in order to protect gas cabinet, only takes this measure, sacrifices volume.This measure is lost more than gain, and holds from cabinet, presses the normal capacity of thin oil seal gas cabinet, has at least 15% dare not use, and the original piston stroke of this rubber membrane gas cabinet is just short, and 15% stroke can not be used, and has wasted very much.If add security personnel's volume again, then there is 25% stroke not use, be very big waste.
Certainly, the piston plate of traditional rubber diaphragm sealed gas cabinet is the epithelium structure, does not have truss to support as skeleton; Be a flexible vault, pressure is fine in bearing, and it is very stable to move upward; But when moving downward; Especially be acceleration when being negative when being a significant slowdown downwards, this piston arch will can make it be damaged in the time of seriously to internal strain.
The model utility content
The purpose of the utility model is to provide a kind of and can enlarges gas cabinet piston that gas cabinet uses capacity and do not damage piston and land automatic buffer device.
The purpose of the utility model is to realize like this; The gas cabinet piston lands automatic buffer device; Comprise piston plate and gas introducing import and export; It is characterized in that: said gas is introduced and is imported and exported the central position that is arranged on the gas cabinet base plate, and said piston plate is that hard and its center promptly are provided with plug members with the corresponding position of said gas introducing import and export.
Above-mentioned plug members is made up of spherical cap and its inner filling thing and is lifted on below the above-mentioned piston plate through iron chains.
In order to make piston get into specified position smoothly, accurate centering of above-mentioned plug members and shutoff above-mentioned gas were introduced and are imported and exported when the assurance piston descended fast, and the gas cabinet lower sides is provided with tubaeform guiding device.
In order further to improve the stability that piston lands, above-mentioned gas cabinet base plate is provided with the piston floor stand.
Above-mentioned gas is introduced to import and export through the gas inlet tube road and is connected with gas inlet and outlet.
In piston decline process fast, the spherical cap on the piston plate can fall into gas and introduce import and export, at this moment; Gas in the gas cabinet can not have been discharged, but because inertia, piston still continues to descend; Because the gas of piston bottom can not be discharged, and is compressed the formation air bag, holds piston conversely; Piston is slowed down, until stopping.At last, slowly discharge in the slit that the gas of piston bottom is introduced on importing and exporting through gas, and piston is fallen the bottom slowly.
The segment diameter of spherical cap must be introduced the diameter of importing and exporting greater than gas when piston landed, and the segment diameter is big more, and it is better that plug members centering gas was introduced the operability of importing and exporting when piston landed, the more little then easier centering of the radius of a ball of spherical cap.The gross weight of spherical cap and inner filling thing should be greater than gas pressure when piston landed.
The utlity model has following beneficial effect, the piston plate of the utility model is hard and when piston lands, leans on spherical cap to cover gas fast and introduce import and export, utilizes piston own wt pressurized gas formation buffer air bag to hold piston simultaneously and slowly descends; Not only improved the performance that piston bears high pressure; And increased the use capacity of gas cabinet significantly, and cause piston plate to damage thereby avoided bumping between piston and the base plate, guaranteed the stability that piston lands; And prolonged working life of gas cabinet; Be applicable to the rubber diaphragm sealed gas cabinet and the gas cabinet of other seal form, simple in structure, safety, reliable.

Embodiment
Embodiment; The gas cabinet piston lands automatic buffer device; Comprise piston plate and gas introducing import and export 4, gas introducing import and export 4 are arranged on the central position of gas cabinet base plate 9 and are connected with gas inlet and outlet 8 through gas inlet tube road 5, and piston plate 10 is a hard; Piston plate 10 centers are promptly introduced import and export 4 corresponding positions with gas and are lifted with plug members 3 through iron chains; Plug members 3 is made up of spherical cap 1 and its inner filling thing 2, and the gas cabinet lower sides is provided with tubaeform guiding device 7, and gas cabinet base plate 9 is provided with piston floor stand 6.
The gross weight of spherical cap 1 and inner filling thing 2 greater than the half as much again of gas pressure to about the twice, too little envelope incessantly, too big swing when causing the piston operation.Small swing is steadily helpful to the gas cabinet piston, can play the effect of pendulum correction.
The segment diameter of spherical cap 1 is introduced the diameter of importing and exporting greater than gas, and the segment diameter is big more, and the operability of plug members 3 centerings was better when piston landed, the more little then easier centering of the radius of a ball of spherical cap 1.The gross weight of spherical cap 1 and inner filling thing 2 was greater than gas pressure when piston landed, and this counterweight is that gas is introduced the pressure that the area of importing and exporting is multiplied by gas in the import and export.
In the present embodiment, gas cabinet is 80,000 m
3Rubber diaphragm sealed gas cabinet, the barrel diameter of gas cabinet are 58m, and it is 2.6m that gas is introduced the diameter of importing and exporting, and the pressure of gas is 3kPa in the import and export, and 800 tons of piston gross weights, the gross weight of plug members are 3.2 tons.If the pressure of gas is brought up to 10kPa in importing and exporting, 2640 tons of piston gross weights at this moment, then the gross weight of plug members is approximately 8 tons ~ 11 tons.The material of spherical cap 1 can be an iron and steel, and inner filling thing 2 is plain concretes.
In piston decline process fast, the spherical cap 1 on the piston plate 10 will fall into gas and introduce import and export 4, and at this moment, the gas in the gas cabinet can not have been discharged from gas cabinet again; But because inertia, piston still continues to descend, because the gas of piston bottom can not be discharged; Therefore be compressed the formation air bag, hold piston conversely, piston is slowed down; Until stopping, slowly discharging in the slit that the gas of last piston bottom is introduced on importing and exporting through gas, and piston is fallen the bottom slowly.
